22 Claims.

This invention pertains to textile apparatus, especially to machines for associating warp yarns or threads with detached loom elements such, for example, as loom stop-motion drop pins or wires, relating more particularly to apparatus of the general type disclosed in the Patent No. 1,- 811,206 granted to Sebastiano Magnano June 23, 1931, and is specifically concerned with improved means for stopping the operation of the mechanism in response to certain eventualities, for example, failure of a Warp yarn to be properly positioned or failure of the apparatus to deliver a drop wire at the proper time and place.

As pointed out in the patent to Sebastiano Magnano No. 1,811,675, dated June 23, 1931, it is usual to arrange the loom-stop drop wires in banks, and in weaving certain types of goods, for instance rayon, it is necessary to deliver successive wires to the several banks in a predetermined order; for instance, in a six-bank arrangement, it may be required to deliver the wires to the several banks in the following order, namely, to bank 1, bank 3, bank 5, bank 2, bank 4 and bank 6. It is obvious that if the machine fail to deliver a wire at the proper time, the next wire to be delivered must be placed in the bank which failed to receive its intended wire, rather than in the next bank, and accordingly any stop mechanism designed to stop the machine upon failure of a wire to feed properly must act with great rapidity in order to avoid over-travel of the de.

livery device. Accordingly one object of the present invention is to provide improved stop mechanism responsive to the failure of a wire to feed properly and which will act so quickly and certainly as to ensure delivery of the next successive wire to the proper bank.

In the operation of machines of this type it sometimes happens that a warp yarn breaks or for some other reason is not properly positioned for the reception of the wire as the latter is delivered, and a further object of the present invention is to provide means operative quickly to stop the machine upon such occurrence. In such machines it is usual to drive all of the parts, including the wire delivery means and the warp picking and positioning elements, in timed relation from a single power shaft, and in such an arrangement, no matter how quickly the stop mechanism may act in response to the breakage of a yarn, it is possible that the warp positioning elements may advance slightly while the mechanism is stopping. Accordingly, before starting again, the position of elements must be turned,

back in order properly to receive the pieced-up.

yarn. However, it is undesirable to try to reverse the wire delivery mechanism, and a further object of the invention is to provide means whereby the warp picking and positioning elements may be turned back slightly without affecting the wire delivery means.

In the machines of this type, as described in the above-noted patents, it is usual intermittently and automatically to advance the mechanism.

- across the sheet of warps so as to permit it to operate upon successive groups of warps. A further object of the present invention is to provide improved simple and. reliable means operative in response to the exhaustion of the warps constituting such a group to initiate movement of the apparatus as a whole to a new position where it may act upon the next successive group of warps.

Other and further objects and advantages of the invention will be made manifest in the following more detailed description and by reference to the accompanying drawings, in which Fig. 1 is a fragmentary side elevation, partly in vertical section, showing so much of a drop wire applying machine of the general type of that of my Patent No. 1,811,206 as is necessary to illustrate the improved stop mechanism and adjunctive parts constituting the present invention;

Referring to the drawings, the numerals l4 and l5 indicate parallel rails such as the rails similarly designated in the above Patent No.

1,811,206. These rails are intended to rest upon the loom frame and to support the drop-wire delivering mechanism while it is performing its in.- tended function. As here illustrated, each rail comprises a longitudinal rack portion R (Fig. 2). The machine is supported on the rails by means of rollers, such as the rollers 5 and 6, designed to travel lengthwise of the rails I4 and I5. One of the rolls 5 and 6 at each end of the machine is furnished with a peripherally toothed portion or pinion which meshes with the corresponding rack B. These pinions engage idler pinions 5*- and 6 (Fig. 1) which in turn mesh with pinions I and 1, respectively, fixed to a shaft 8 which corresponds in function to the shaft 8 of my prior Patent No, 1,811,206. This shaft 8 is journaled at opposite ends in the end members I and 2 of the machine frame, said end members being rigidly united by the longitudinally extending front and rear rails 3 and 4, respectively (Fig. 2) The upper edges of therails 3 and 4 provide a trackor guideway along which travel flanged rollers (not shown) supporting a movable carriage C which, in general, is similar in construction and function to the magazine supporting carriage of my aforesaid patent, said carriage comprising spaced parallel side walls 3- and 4 and end members I and 2 (Fig, 2).

A motor M mounted on the machine frame drives speed reduction gearing (not shown) in a box I5 in which is journaled the longitudinally extending shaft I6. As here illustrated, this shaft is provided with a cam I'I having a groove I3 which receives a cam follower I9 mounted on the carriage C whereby the rotation of the shaft I6 causes the carriage to move back and forth along the rails 3 and 4.

The carriage C supports the drop-wire magazine (not shown), which may be like that of Patent No. 1,811,206 or otherwise, as desired, together with the corresponding accessory elements and mechanism (including rolls hereinafter more fully described) necessary to deliver Wires one by one in properly timed relation and in position to be received by a properly disposed warp yarn.

.The machine frame has. spaced depending brackets 20 and 2I (Fig, 1) which carry supporting members 22 and 23 or the equivalent from which project the fingers 24 corresponding in number to the number of banks of wires to be placed on the warps and functioning like the fingers 26I of Patent No. 1,811,206. The brackets 20 and 2| also support transverse bridge members 25 and 26 upon which are mounted sets of warp manipulating elements corresponding in construction, arrangement and function to the warp manipulating elements of my aforesaid patent. Among such elements is the rocking warp positioner 21 (Fig. 3). The warp positioner 21 is mounted to rock on a fixed stub shaft 28 projecting from the support 25 and is rocked by appropriate connections (not shown) once for each drop wire delivered. This warp positioner 21 carries a long projecting pin 29 substantially parallel to the shaft 28 and which projects to the left of the positioner as viewed in Fig. 1.

The gearing in the box I5 includes a clutch (not shown) whose parts may be relatively separated to stop the drive of the carriage and the other parts of the machine. The operation of this clutch is controlled by a shaft 30 (Fig. 3) extending from front to rear of the machine and provided at its forward end with an actuating handle 3|. The shaft 30 is also provided with a laterally projecting stud 32 having an inclined cam face 33 engageable by a roller 34 carried by an arm 35 fixed to a sleeve 36 turning on the shaft 8, By engagement of the roll 34 with the cam face 33 the shaft 30 may be rocked and the clutch parts disengaged, thereby to stop the machine.

Mounted on the shaft 8 is a lever 31 (Figs. 1 and 5) to the lower end of which is connected a link 38 (Fig. 3) which is constantly reciprocated while the machine is running by means (not shown) within the gear box I5, thereby constantly rocking the lever 31 from front to rear. The lever 31 is bifurcated at its upper end, its legs being shaped to form disk-like journal members'40 (Fig, 5) having aligned journal openings for the reception of shaft 8. Between the legs is disposed a ratchet wheel 39 which is fixed to the shaft 8. At opposite sides of the ratchet wheel 39 are disposed collars 40 which turn on reduced portions of the disks 40, the collars having projecting segmental arms 4I between which is fixed a, weight 42 which tends to turn the collars in a clockwise direction, as viewed in Fig. 4, so far as is permitted by a fixed stop. A curved guard plate 43, substantially concentric with the ratchet 39, projects downwardly from the weight and is normally interposed between the teeth of the ratchet and a pawl 44 mounted on the lever 31. During the normal operation and so long as warps are positioned in readiness to be picked, the pawl is id1e,,being held out of contact with the ratchet by the guard plate 43,.but when it becomes necessary to move the machine along the sheet of warps. to enable it to manipulate the warps of a new group. the guard plate 43, which normally follows: the lever 31 as the latter swings, is held stationary as hereinafter more fully described, and the pawl slips off of its free extremity and operatively engages teeth of the ratchet 39, there.- by turning the shaft 8 and advancing the entire mechanism along the rails M and I5 The drop-wire delivery mechanism includes a pair of intermittently acting feed rolls 45 and 46 (Fig. 1), the roll 46 being mounted in fixed bearings in a bracket 41 supported by the carriage while. the roll 45 is journaled in a frame which rocks about a shaft 48 supported by the bracket 41. The frame which carries roll 45 is urged in auclockwise direction by a spring (not shown) and has an upwardly extending arm 49 which has pinand slotconnections at its upper end with the shorter. arm 50 (Figs. 1 and 3) of a bell crank lever. pivotally supported by the carriage and having a long bent arm 5| whose free end overlies a slidable, normally stationary transmitter 52 freely movable along the upper edge of the frame member 4. This transmitter slide 52 has notches 53 in its upper edge for the reception of a downwardly directed dog 54 at the end of the lever arm 5I. The notches 53 have vertical end walls,.but a second, fixed plate I52, parallel to plate 52,. has elongate notches I53 having inclined end walls constituting cams for raising the dog 54' out of any notch 53 with which it may be engaged after the plate 52 has moved far enough to operate the stop devices, as here after more fully described, but before the engagement of the dog and slide 52 can block the normal travel of the carriage,

The number of notches 53 corresponds to the number of banks of drop wires to be placed on the warp, the notches being equally spaced and so arranged that whatever position the carriage may occupy when a drop wire fails to feed properly, the dog 54 will engage a notch 53 and cause the machine to stop before the carriage can have moved to the wire delivery position corresponding to the next bank. Thus, whereas in the machine of Patent No. 1,811,675 the carriage might continue to move through a substantial distance, after failing to deliver a wire, before stopping and thus, when again started, fail to place wires in intervening banks, the present arrangement makes it impossible to skip a bank when restarting the machine after a stop resulting from failure to deliver a wire. I

The sleeve 35 is provided with an arm 55 (Figs. 1 and 4) at the end opposite to that at which the arm 35 is mounted, and the arm 55 is furnished at its lower end with a substantially vertical abutment shoulder 56 at its rear side (Fig. 4). A motion transmitting arm 51 is pivotally supported by the lever 37 with its free end normally disposed below the shoulder 56. A lifter arm 58 normally underlies the free end of arm 51, the arm 58 being fixed to a rotary shaft 58 journaled in bearings carried by the frame member 5 and extending parallel to the shaft 8. The shaft 58 is provided with a pair of oppositely directed, normally horizontal actuating arms 59 and 65 (Fig. '7).

A bell crank lever having a substantially horizontal short arm 51 (Fig. 1) is pivotally mounted on the bracket 25, and the lever arm 51 carries a pair of horizontal spring fingers S2 and 53 (Figs. 1 and 7) which overlie and underlie respectively the arms 59 and 69 of the shaft 58. This bell crank lever also has an upwardly directed arm 64 whose upper end engages a notch in the lower edge of the slide member 52.

Pivotally supported upon the frame member 4 is a lever 65 (Figs. 1 and 6) having at its lefthand end, as viewed in Fig. 1, an abutment block 66 (Fig. 6) which at times may be lifted so as to be interposed between the front face of the frame member 4 and a yoke 51 which unites and projects from the collars Ml. When this abutment block is so interposed between the memhers 4 and 61, it limits rocking of the collars relatively to the lever 31, thus holding back the guard plate 43 and allowing the pawl 45 to act on the ratchet wheel 35, thereby to turn the shaft 8 and advance the machine along the rails as above referred to.

The lever 65 has an arm 58 to which is connected one end of a wire 69. The lower end of this wire is connected to a lever 10 (Fig. 6) mounted to swing on the stub shaft 28 above referred to, the lever 10 being normally held in a substantially horizontal position by a light spring or weight. A detector arm 12 (Fig. 3) is also mounted on the shaft 28 and is urged in a clockwise direction by a spring (not shown), but normally follows the movement of the warp positioner 21 since the arm 12 overlies the pin 29 which projects from the positioner as above described. When the warp positioner is in its upper position, it holds the arm 12 up in the full line position shown in. Fig. 6, but each time the member 21 moves downwardly the detector arm 12 is permitted to drop. If its free end then engages warps W (Fig. 6) properly positioned at the advancing or front side of the machine to be manipulated by the warp-positioning elements, it is stopped before a laterally projecting pin 12 carried by the arm 12, engages the arm 10. However, if no warps are present, the end of the arm 12 moves down to the broken line position of Fig. 6, and its pin l2 engages the lever l and rocks the latter downwardly, as shown in Fig. 6. The wire 69 is thereby pulled downwardly, thus rocking lever 68 whereby the abutment block 66 is positioned to limit movement of the member 51. The pawl 41 is thus allowed to act and the machine is shifted along the rails M and 15 until a new group of warps is available for picking and for holding the detector arm 12 in its upper inoperative position.

In order to stop the machine if a warp yarn breaks or is absent from wire-receiving position (even though the machine be properly located with reference to a group of warps) a feeler finger '13 (Fig. 4) is provided. This finger is mounted to swing on the shaft 28 and is normally urged in a clockwise direction (Fig. 4) by a spring or weight but is controlled in its movements by the pin 29 projecting from the yarn positioner 2'1. A bell crank lever is also pivoted to swing on the shaft 28 and comprises a normally horizontal arm M which is disposed in the path of a pin '15 projecting laterally from the feeler 3-3. The bell crank has a second arm 16 to which is attached one end of a wire ii; the other end of the wire T! is connected to an arm 78 (Fig. 4) fixed to the shaft 53. The feeler i3 is raised and lowered by the pin 29. If, in its descent, its end engages a warp yarn W properly positioned for picking (and supported for this purpose by a pair of parallel spaced members 19) the feeler is arrested, but if, on the other hand, no warp yarn is present, the feeler continues to drop;its pin "15 engages lever arm M and rocks the arm 76 downwardly, and the wire T? is thereby pulled and thus rocks the shaft 58. The arm 58 carried by the shaft 58 as above described, is thereby raised and lifts the motion-transmitting lever up far enough to contact the abutment shoulder 56 as the lever 31 rocks forwardly, the lever 57 thus being interposed between the parts 31 and 55. Thus the sleeve 36 is rocked and with it the arm 35 which in turn rocks the cam stud 32 and turns the clutch shaft 35, thereby stopping the machine. If the slide 52 should be actuated when lever 5'! is directly below the end of arm 55, one or the other of fingers 62 or 63 will yield, thus avoiding breakage of parts.

The wire delivery feed and the warp picking and positioning devices are driven in timed relation by a drive shaft 12 (Fig. 8) actuated by gearing (not shown) in the box 15. The wire delivery feed receives its motion from shaft i2 through suitable connections including a gear 19 (Fig. 8) keyed to an enlarged portion 50 of the shaft 12. The key 8! is fixed in the part 80 but the keyway 32 in the gear is widened so as to permit lost motion between the parts l9 and 80. When the parts are turning in the normal or forward direction indicated by the arrow (Fig. 8), the wire feed devices are driven in accurately timed relation to the warp positioning elements which are driven positively by the shaft l2 regardless of the direction of rotation of the latter, but if it become necessary to reverse the shaft i2 slightly in order accurately to set the warp-positioning elements, this may be done without reversing the wire delivery mechanism by reason of the freedom of the key 8! to move backwardly in the keyway 82.

If, diuing the operation of the machine, a wire fail to feed down between the rolls 45 and 46 at the proper time, the rolls abnormally approach and the arm 58 is swung so as to drop the dog 54 far enough to engage one of the notches 53 as the carriage moves in one direction or the other.

When the dog enters any one of the notches, the continued movement of the carriage causes the transmitter slide 52 to move longitudinally in one direction or the other, thus swinging lever arm 64 and causing one or the other of the spring fingers 62 or 53 to engage one or the other of the arms 59 or 69, respectively. The shaft 58 is thereby rocked so as to raise the arm 58 and thus lift motion-transmitting lever 51 high enough to engage abutment shoulder 56 as the lever 31 is rocked rearwardly, thus turning the sleeve 36 and actuating the clutch shaft 30 as above described to stop the machine immediately and before the carriage can move to the next wire-delivery position.

By reason of the construction above described it is manifest that the machine will be moved along the rails l and l5 automatically in response to exhaustion of a given group of warps and thus placed in readiness for manipulating a new group of warps. Furthermore, it is apparent that upon failure of the machine to deliver a drop-wire properly or upon absence of a warp yarn, either by breakage or otherwise, from the position which it should occupy to receive a drop-wire, the machine will be very quickly brought to rest so that overtravel and improper subsequent operation is substantially prevented.

While a certain desirable embodiment of the invention has herein been illustrated by way of example, it is to be understood that the invention is not limited to this precise embodiment but is of broader application and inclusive of all equivalents and substitutions of parts such as fall within the scope of the appended claims.
